Studies of Microwave Shear Waves in Solids

Abstract

Due to the slower velocities and the transverse wave nature, microwave shear waves have interesting theoretical properties and important practical application. Theoretical and experimental investigation of microwave shear waves in solids were conducted with emphasis on the efficient generation of microwave shear waves and on the theory and application of the parametric interaction of microwave shear waves and light. Efficient shear wave transducers make possible the study of the interaction of light and microwave shear waves in solids. In microwave frequencies, the interaction of light and microwave shear waves is in the Bragg diffraction region. We have used a laser as an optical probe to map the energy distribution of shear waves, to measure the attenuation, to estimate the mode conversion efficiency of a YAG mode converter, and to determine the reflection and transmission coefficients of shear wave bonds. We have also demonstrated the second feature of shear wave diffraction in measuring quantitatively the acoustic birefringence in a (110) oriented YAG rod.
